According to my archeological research, it was originally designed to reuse `::` as namespace separator, but it was finally changed to something else due to ambiguity between static class elements and namespaced functions/constants. See https://wiki.php.net/rfc/namespaceissues and https://wiki.php.net/rfc/backslashnamespaces (where `::` is assumed to be the namespace separator). —Claude
